ADOLPH SAMSON, OF BUFFALO, NEWV YORK, ASSIGNOR TO PRATT & LETCH VORTH, OF SAME PLACE.

MACHINE FOR ATTACHING EYEBOLTS TO HAME-RINGS.

SPECIFICATION forming part of Letters Patent No. 410,771, dated September 10, 1889.

Application filed April 12, 1889.

To all whom it may concern/.

Be it known that I, ADOLPH SAMSON, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Machines for Attaching Studs or Eyebolts to flame-Rings, of which the following is a specification. I

This invention relates to that class of machines which are designed more especially for attaching the studs or eyebolts to hamerings, whereby the rings are secured to the body of the hame.

The object of my invention is to produce a simple and compact machine of this character; and the invention consists of the improvements which will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical sectional elevation of my improved machine. Fig. 2 is a longitudinal section in line a w,Fig. 1. Fig. 3 is a horizontal section in line y 1 Fig. 2. Fig. 4 is a detached crosssectional elevation of the compressing-dies and the reciprocating follower, showing the stud or eyebolt attached to the hame-ring. Fig. 5 is a fragmentary sectional elevation showing the stud or eyebolt in position ready to be pressedby the dies. Fig. 6 is a perspective view of a hame-rin g with the stud or eyebolt attached thereto.

Like letters of reference refer to like parts in the several figures.

A represents the vertical frame of the machine, consisting of two vertical standards a a, connected at their upper ends by a crossbar a and supported at their lower ends upon a bed or table A.

0 represents a hollow rectangular frame secured to the bed A, between the standards of the frame A, by flanges 0, formed on the front and rear walls of the frame 0 and bolted to the bed A.

D D represent rectangular blocks or dies secured, respectively, to rock-shafts d d, which are journaled in the end walls of the rectangular frame 0. Thedies D D are arranged side by side and at a sufficient distance from each other to permit the ready insertion of a hame-ring 6 between the two dies,

Serial No. 307,009. (No model.)

as shown in Fig. 1. The dies D D are each provided with a fiat upper face having a transverse groove (1 for the reception of the stud-blank f. The back or rear sides of the dies D D are provided with vertical shoulders which bear against shoulders g, formed on the upper ends of the front and rear walls of the frame 0, when the upper faces of the dies are in a horizontal position, as shown in Fig. 1. The inner or adjacent face of each die is provided with a semicircular recess or groove (Z and above this recess the adjacent face of each die is slightly tapered or rounded off, forming a compressing-face d The shafts d d of the dies D D are provided with suitable gears h, whereby the dies are caused to rock toward and from each other by the movement of a rock-arm e, secured to the shaft of one of said dies. The upper faces of the dies D D are held in a horizontal position by means of a spring I, which rests upon the bed A and bears against the under side of the rock-arm t', secured to one end of the shaft of one of the dies. The spring I, bearing upwardly against the free end of the arm t', holds the dies with their rear shoulders g in contact with the shoulders g of the frame 0 and the compressing-faces of the dies apart, to permit the ready insertion of a hame-ring between the two dies.

J represents a crank-shaft journaled in the upper portion of the standards of the main frame A and provided with a driving-wheel J.

K represents a vertically reciprocating cross-head arranged between the standards a a and connected with the crank-shaft J by a rod 10. The cross-head K is guided between ways secured to the inner sides of the standards.

L represents a pusher plate or follower secured to the front side of the cross-head K, centrally above the dies D D. The follower L is bifurcated at its lower end, so as to form two depending fingers Z Z, which descend between the two dies D D upon the downward stroke of the cross-head K.

. 1% represents a vertical slide-rod, which is guided in ways or brackets m ,secured to the front side of the standard a of the main frame and rests with its lower end upon the free end of the rock-arm 2'.

n represents a forwardly-prejecting lug or arm formed on one side of the cross-head K and overhanging the upper end of the sliderod m. The lug n is provided with an adj ustable screw-bolt n, which engages against the upper end of the slide-rod at the last portion of each downward stroke of the cross-head, causing the slide-rod to move downwardly with the cross-head. During the downward movement of the slide-rod the free end of the arm i is moved downwardly, causing the compressing-faces of the two dies to be moved toward each other until the slide-rod is re leased by the upward movement of the crosshcad, when the dies are returned to their former position by the spring 1. During the upward movement of the cross-head the studblank f is placed in the groove (1*, formed in the top faces of the two dies with the hamering suspended therefrom and hanging downwardly between the dies, as shown in Fig. 1. As the cross-head descends, the dependingfingers ll of the follower come in contact with the hamc-ring on opposite sides of the stud-blank and force the hame-ring downwardly between the dies,which movementben dsthe stud-blank partly around the ring, as shown in Fig. 5. During the last part of the downward movement of the follower the dies are turned inwardly with their compressing-faces toward each other, which movement closes the eye or loop of the stud around the ring and firmly attaches the stud to the ring. Upon the upward movement of the follower and crosshead the dies are turned baclnvardly by the spring bearing against the under side of the arm '2', and the hame-ring with the stud attached thereto allowed to drop from between the dies.

By the use of my improved machine the studs or eyebolts can be attached to hamerings very rapidly and at a single operation.

I claim as my invention-- 1. The combination, with the dies D D, provided with flat upper faces adapted to support a stud-blank, and a ring suspended from said blank, of a vertically-movable follower provided with depending fingers engaging over said ring on opposite sides of the blank, substantially as set forth.
